美國丹娜-法伯癌症研究所Toni K. Choueiri、紀念斯隆-凱特琳癌症中心Robert J. Motzer等研究人員合作報導了avelumab+阿西替尼與舒尼替尼在治療晚期腎細胞癌中的比較。相關論文於2020年9月7日在線發表在《自然—醫學》雜誌上。
研究人員報告了來自JAVELIN Renal 101三期臨床試驗(n=886;NCT02684006)基線腫瘤樣品的分子分析的結果,該試驗證明一線avelumab+阿西替尼與舒尼替尼在晚期腎細胞癌(aRCC)中顯著延長了無進展生存期(PFS)。研究人員發現,在任一研究組中,既不表達通常評估的生物標誌物PD-L1,也不表達腫瘤突變負擔區分的PFS。同樣,FcR單核苷酸多態性的存在也沒有影響。
研究人員確定了與治療組之間差異PFS相關的重要生物學特徵,包括新的免疫調節和血管生成基因表達特徵(GES)、先前未描述的突變概況及其對應的GES,以及幾種HLA類型。這些發現提供了對PD-1/PD-L1和血管生成途徑聯合抑制反應決定因素的見解,並可能有助於開發改善aRCC患者的治療策略。

Abstract: We report on molecular analyses of baseline tumor samples from the phase 3 JAVELIN Renal 101 trial (n=886; NCT02684006), which demonstrated significantly prolonged progression-free survival (PFS) with first-line avelumab+axitinib versus sunitinib in advanced renal cell carcinoma (aRCC). We found that neither expression of the commonly assessed biomarker programmed cell death ligand 1 (PD-L1) nor tumor mutational burden differentiated PFS in either study arm. Similarly, the presence of FcR single nucleotide polymorphisms was unimpactful. We identified important biological features associated with differential PFS between the treatment arms, including new immunomodulatory and angiogenesis gene expression signatures (GESs), previously undescribed mutational profiles and their corresponding GESs, and several HLA types. These findings provide insight into the determinants of response to combined PD-1/PD-L1 and angiogenic pathway inhibition and may aid in the development of strategies for improved patient care in aRCC.
